' VENTI ATING wrnnow' Application filed January 9, 1931. Serial No. 507,635.

This invention relates to windows and the object is toprovide an improved wlndow sash assembly of'the character disclosed in my co-pending applications Serial No 455,-

showing the parts in a different position 851, filed May 26,1930 and Serial No. 458,509, filed May 31, 1930. I

In these prior applications I have disclosed *a sash assembly including a lower sash mounted to. slide in vertical channel guides attached tothe opposingjambs of the window frame. The lOWGI'SQCtlOllS of the guides are mounted to swing to an angular position out of alignment with the upper section in order to facilitateremoval or reglazing of the .lower sash. One of the advantages of this arrangement, in addition to providing for removal and reglazing of the lower sash, is that the lower sash may be supported inan angular position so that a ventilating opening is provided between the upper edge of the low er sash and the adjacent lower edge of the upper sash. There is, however, a disadvantage incident to theuseof this arrangement for ventilating purposes in that moisture and air is permitted to pass directly through the lower portion of the window frame between the window jambs and the adjacent lower guide sections and this is not altogether desirable either from a weatherproofing or a ventilating standpoint. I v

In order to correct this detect, the present i invention contemplates the provision ofwing plates attached to the window jambs and adapted to fit closely against the lower guide sections to prevent the leakage of air or moisture between these sections and the window jambs when the sections are swung to an inclined position for ventilating purposes.

.These wing plates are also utilized to limit 7 the angular movement of the lower guide sections with reference to the upper guide secer guide tions and, consequently, take the place of the 1 stop members previously employed for this purpose. The wing plates are also equipped with friction shoes engageable with the lowsections to hold the latter in various. positions of angular adjustment.

Proceeding now to a more detailed discussion of the invention, reference will be had to V the a cc'ompanying drawings, wherein Figure .1 is a perspective view of a window assembly equipped with sash guides constructed 1n accordance with this invention.

Referring moreparticularly to the drawings, 11 designates a window frame equipped with a stationary. upper sash 12and a sliding lower sash 13. The side edges ofthe lower sash are arranged to slide in vertical channel guides attached to the window janibs 14 and extending the full height of the window frame. Each guide comprises a station- ..ary upper sect1on15. and a pivotally mounted lower section 16., Both. sections are formed from a single stripof lnetal bent to provide spaced sash engagingfl-anges 17 and 18 connected by an intervening web 19. The web 19 of section 15 is rigidlysecured to the web 20 of a channel shaped base strip including side flanges 21 and 22. The web 201 ofthe base strip is spaced from the window amb, ltby the flanges 21 and 22 and is secured in place by the screws 23.; The, base strip is also; provided with an"additional fiange 24 vwhich is preferably formed as an integral continuation of the flange 22 and is arranged to project beyond the web 20 in the opposite direction, i. e., away from the amb 14. At its lower end the web 19 of the sash guide section 16 is secured'by a pivot 25 to the web 20 of the base strip, whereby said section 16 is mounted to swing into and out of alignment with the upper complementary section 15. When the guide sections 15 and 16 are aligned the flange 2410f:

the base strip serves as a weatherproofing element preventing leakage of air or moisture between the web of the base. strip and the engaging webs of the sections 15 and16. The guide sections 15 and 16 arealso preferably provided with weatherprooflng flanges 26 formed as reverse continuations of the sash engaging flanges 18 and arranged to overlap the. flange 21 of the base plate. As shown to advantage in Figs. 3 and 4: the web 20 of each base strip and the engaging web 19 of the pivotally mounted guide sections 16 are provided with complementary openings 27 to receive the bolt or detent (not shown) carried by one of the sash locks appearing at 28 in Fig. 1.

When the complementary sections 15 and 16 of each guide are aligned they form a channel guide for the sash 13 which extends from the bottom to the top of the window frame 11 so that the said sash 13 has the usual range of sliding movement. When the sash 13 is positioned between the lower sections 16 and the latter are swung to the position. shown in Figs. 1 and 3, a ventilating opening is provided for the admission of outside air which is deflected upwardly in a desired manner by the inclination of the sash. When the sash 13 is in this position it is desirable that all of the incoming air be directed over the upper edge of the sash and that no air or moisture be permitted to leak upwardly between the opposing surfaces of the window jamb 14 and the guide section 16. This is provided for in the present instance by wing plates 29 arranged to fit closely against the outer side surface of the guide sections 16 during swinging movement of the latter to the position shown in Fig. 3. The wing plates are shown as formed integral with the flanges 21 of the base strip, but it will be manifest that these plates may be attached to the base strip or to the window jambs 14 in various ways to serve the purpose for which they are provided. The wing plates are preferably made of gradually decreasing width from the upper to the lower ends in order to save metal since the manner of pivoting the guide sections 16 does not requirethe lower portions of the wing plates to be of the same width as the upper portions. The free longitudinal edges of the wing plates are preferably rolled as indicated at and provided with suitable stiffening or reinforcing rods 31. These rolled edges 30 serve as stops engageable with the guide sections 16 when said sections are swung to the position shown in Figs. 1 and 3.

A casing 32, open at the bottom, is provided at the upper edge of each wing plate 29. The flange 26 of each guide section 16 terminates, at its upper end, in a guide lug 33 which is spaced from the web 19 to provide an intervening guide slot 34 receiving the inner side wall of the casing 32. The lug 33 extends upwardly within the bottom portion ofthe casing 32 and is formed with a rounded upper end 3364 bearing against a spring pressed friction shoe 35. This shoe consists of a flat metal strip having its outer end resting loosely on the upper extremity of the rolled edge 30 and its inner end resting loosely on a block 36 attached to the flange 22. A plurality of coil springs 37 are interposed between the strip 35 and the top wall of the casing 32 and serve to press the strip downwardly against the rounded terminal of the lug 33. Longitudinal movement of the strip 35 in the casing 32 is prevented by bending the inner end of the strip downwardly as at 34a to en'- gage in a slot 350: between the block 36 and the flange 22. Adjacent the block 36 the strip 35 is bowed upwardly to provide a depression 39 in which the rounded upper end of the lug 33 is firmly held when the guide section 16 is aligned with the guide section 15.

The pressure of the strips 35 on the lugs 33 is sufficient to hold the guide sections 16 and the sash 13 in various positions of angular adjustment and thereby enables the effective width of the ventilating or air flow passage to be regulated as desired.

The continuous pressure exerted by the springs 37 on the lug 33 also serves to prevent rattling of the guide sections 16 in any position to which said sections are moved with reference to the upper guide section 15.

In addition to providing for efficient ventilation, the arrangement described in the foregoing permits the sash 13 to be easily and quickly removed when the guide sections 16 are positioned as shown in Fig. 1. Moreover,

reglazing of thesash 13 may be conveniently accomplished (by raising the sash in the guide section 16) when the latter are positioned as shown in Fig. 1 if the top rail 1% of the sash is projected a sufficient distance above the guide sections to permit convenient removal of the angle straps 13a and the top sash rail 135 these parts appearing in Figs. 1 and 2 and being of the same construction as disclosed in my co-pending application Serial No. 458,509.

For reglazing purposes, the sash is held in its elevated position by engaging the detents (not shown) ofthe locks 28 in certain of the detent receiving openings provided along the length of the guide sections 16. After the reglazing operation the rail 19 is again "fastened in position and thesash 13 lowered to the bottom of the guide sections 16 so that said sections maybe returned to aligned position with reference to the guide sections 15.
